Not sure how to comment on your problem there.
My wipeout 2097 demo is not at all buggy and is working fine.
the only thing I have done is made sure that I have retrieved all the up to date libraries and the like at the time.
another note, I had also found that there were some libraries missing after my os4.1 install, for older rtg type games. I know this sentence off topic.
another off topic sentence, does crossfire 2 demo work, shogo or heretic 2 on your os4.1??
Shogo demo is a tad tempromental on my sam440ep, but it usually works if you keep moving. when you stand still thats when I get DSI for some reason?
i know I got things like warcraft 2, doom type games, hexen, feeble files was working(not sure what I did last for it not to work) Descent, etc, etc.
try chromium BSU, I like this game.
Get the stratagus.lha, and with it comes invasion - Battle for survival game also.
How is your DVplayer working on os4.1? I noticed that I was missing a library and codec, when a fellow os4.1 user told me his setup in LIBS.
Anyway, not sure if I even helped you, but it'll be worth checking out the versions of all your libraries that the wipeout game may require to use? Maybe there is a newer version of something needed. OS4depot ofcourse, should have it.
